HP ENVY 14 - GPU Clock and Undervoltage POLL

The GPU is designed to take more voltage and higher clocks so this particular OC should not create an additional wear.

 

Higher clocks shouldn't cause increased wear, or at least not in any noticeable manner. Voltage increases are more important, but that's not what we're doing here.

 

Is there a detailed guide to over clocking an envy, including warnings?

 

Modding the BIOS for faster HD5650 clocks

The higher GPU clock speed can be set in the vbios itself which is stored in the system bios. Unpack the Insyde BIOS with Phoenixtool, open the 60-64kb VBIOS file with RBE, change the clocks to the high speed, then repackage back with PhoenixTool.

Another possibility: could do extract the faster-clocked VBISO from an Acer 4820TG and inject it instead in the Envy 14 bios.

If testing this modification then be aware of the BIOS emergency recovery process here.

Would probably be a good idea for a pioneer to do the bios mod, test it and package it for the enjoyment of other Envy 14 owners.

 

nando, I just went to give this a try.
I downloaded the latest version (1.57) and BIOS (F13A) I try to open the BIOS with phoenixtool.exe and it tells me the BIOS is not supported.
Am I doing something wrong?

 

Not sure. I don't have an Envy 14. Might be HP's customisations of the Insyde BIOS that prevents PhoenixTool from being able to decompress the bios. Probably a good idea to ask the PhoenixTool makers to investigate.

 

OK will go and sign up on that forum.

Would be great to get my 5650 above 500

 

Overclocked mine to 545/800MHz, anything over crashes after about 20 minutes. I'm wondering which is more important, core clock or memory? Which will give me a bigger boost. Also, has anyone increased the voltage on it? Correct me if I'm wrong but it also came undervolted didn't it?

 

Please tell me if you find a way of doing it. I'd like to get mine to 550/850MHz.

 

No joy

The tool couldnt read the HP BIOS. Gutted.
